How to download songs on guitar hero III?

Top Voted Answer

With your PS3 hooked up to the Internet, go to the PlayStation Store, then Add-Ons. There will be a link to Guitar Hero III: Legends of Rock there (if not, select G and then to Guitar Hero III). Then you will be able to select songs for purchase (you will need a credit card or entropay account for the ones that cost). Once you have paid (of course, unless it's a free song), download the song(s). Back on the XrossMediaBar (the PS3's home screen), after the downloading is complete, select Install, wait for it to finish, then enjoy your new songs on the game!
